RNA, NK Type

RNA, NK Type

RNA, NK type needle roller bearings, this type of bearing has no inner ring, it is suitable for the support structure with limited radial installation size, and the journal matched with the bearing is directly used as the rolling surface. As the shaft of the raceway surface, the hardware must be hardened and ground, and only when it is processed to the appropriate size and shape accuracy, the entire set of needle roller bearings can have a high life and running accuracy. At the same time, since there is no inner ring, the diameter of the shaft can also be appropriately enlarged, thereby increasing the rigidity.

NA, NKI Type

There is an inner ring NA.NK type needle roller bearing. Since the inner ring has no rib, the inner ring, outer ring, a full set of needle rollers and cages can be installed separately, and the axial displacement of the shaft or housing is not restricted. Since the needle rollers are separated by a cage, the friction is reduced, so it can be used in parts with high rotation speed.

Needle Roller Bearings HK 2526

Needle Roller Bearings HK 2526

HK 2526 needle roller bearings, with an inner diameter of 25mm, an outer diameter of 32mm, and a length of 26mm, are compact and suitable for equipment with limited space. Made of high-quality alloy steel, they have high hardness and strong wear resistance to ensure long-term stable operation. Their needle roller design can achieve a large load-bearing capacity in a small space and effectively transmit radial loads. Commonly used in automotive engines, transmissions, precision instruments and other fields, they play a key supporting role in compact structures and help equipment operate efficiently.

Needle roller bearings are roller bearings with cylindrical rollers. Relative to their diameter, the rollers are thin and long. This type of roller is called a needle roller. Despite its small cross-section, the bearing still has a high load bearing capacity. Needle roller bearings are equipped with thin and long rollers (roller diameter D≤5mm, L/D≥2.5, L is the roller length), so the radial structure is compact. When its inner diameter size and load capacity are the same as those of other types of bearings, the outer diameter is the smallest, which is particularly suitable for support structures with limited radial installation dimensions.
